Ty suddenly had an idea. He hated his life. He hated his home, his foster family, the town he lived in and the school he went to- he was sick of it all. But with his newfound powers, he could reshape his entire existence! He could be reborn as someone he actually liked being!
Before he started, he wished to himself, "I wish that no matter what happens to me, I maintain full awareness of my existence, my surroundings and my intelligence." With a little tingle, he recognised this wish had been granted. Then, taking a deep breath, he wished, "I wish I could go back into the womb and choose every aspect of who or what I'll become."
Suddenly, the world around him began to blur. Before he knew what was happening, he was stark naked, and all of reality seemed to be laid out in front of his unfocused eyes. He felt like he could see every possibility in all of existence- his ability to be anything, from himself, to a billionaire playboy, to a colossal blue whale, to a tiny amoeba.
This distracted him from his physical regression. He steadily shrunk to the size of a newborn baby, regressing and getting ever smaller until, for a few brief seconds, he was a screaming newborn. Within seconds, he retreated into the warmth of his mother's womb. He paused to think for a moment, before making a further wish.

His arms and legs receded even further, his genitalia defused before dissolving into nothingness, and his human characteristics rapidly dwindled until he was a xygote wedged in his mother's womb. At that point, he felt himself being dragged away from this resting point, and then a part of themselves split off, and Ty realized this was the sperm being extracted from what they were now, the ovum awaiting the genetic material to form into a human.
Able to wait in this moment for as long as they wanted, Ty considered the options this gave him...
